HAProxy ALOHA Documentation 12.0

Diagnostic Tools

To troubleshoot HAProxy ALOHA, you use the DiagTools tab to run diagnostic tools from the user interface.

DiagTool web form

The DiagTool tab displays the following form composed of these elements:

https://cdn.haproxy.com/documentation/aloha/12-0/assets/diagtoolstab-d844f03bf204fb53da565a4cbc1df43fec27a480d58fef0bf89ee154e692b8eb.png

The web form is composed by the following elements:

  1. Diagnostic tool to run

  2. Depending on the tool, number of tries or occurrence to capture

  3. Maximum time to run the diagnostic tool

  4. Tool option #1

  5. Tool option #2

  6. Tool option #3

  7. Output from the tool

Certain tools can take on options. These options are described in the command line to run. If an option name is followed by an asterisk *, it is not mandatory.

Use the ping tool of the form above with two options: one optional, one mandatory.

  • option #1: source IP to use.

    Optional, since HAProxy ALOHA automatically uses the best IP for the destination

  • option #2: destination IP to reach

  • option #3: not used
